Why doesn't the brain rest?

It depends on what you mean by "rest." The brain always has different levels of activity; some mental processes may use many areas of the brain while at other times the brain may be not as active. However, the brain is never completely inactive - if it is, then the organism is no longer living. Every bodily function is a result of the brain's work, and even when sleeping, the brain might be very active.
